v0.7.0

• Add support for text notes to be attached to features in a Feature Layer. #6
• Consolidation of placement-related options into a single placement object:
  • placementHint => placement.hint
  • placementAlignments => placement.pointAlignments (clarify usage)
• Addition of placement.outsidePolygon option to allow polygon notes to be allowed to move outside the polygon interior (default), or to be constrained to the interior.
• Update note position when its target graphic geometry changes (position and/or shape, e.g. when using sketch tools to move or reshape a drawn graphic).
